AEC-Q100 qualification means this part has passed the automotive-grade reliability stress tests: temperature cycling, ESD, latch-up, and extended high-temperature operating life. It is suitable for under-hood and cabin-domain applications where a standard commercial oscillator would be rejected at PPAP. ## Supply voltage range 1.8V to 3.3V — one part covers three rails The wide supply range lets the same oscillator serve 1.8V, 2.5V, and 3.3V logic domains without a dedicated LDO. A 3.3V MCU and a 1.8V FPGA can share the same BOM line — the oscillator's output swing tracks the supply rail, so the CMOS input threshold is always met. Maximum supply current is 7.2 mA at 54 MHz — well within the budget of a typical automotive power tree. When the system enters sleep, the standby (power-down) function drops consumption to 15 µA max, preserving battery life in always-powered modules like a body controller or telematics unit. ## Package and footprint — 2.50 mm x 2.00 mm 4-SMD no-lead The 4-SMD, no-lead package measures 2.50 mm x 2.00 mm with a seated height of 0.90 mm. The small footprint and low profile suit space-constrained automotive modules like camera ECUs or radar sensor boards. The no-lead construction reduces parasitic inductance compared to a through-hole crystal can, improving EMI margin at 54 MHz.","metaTitle":"DSC1001DI1-054.0000T – Microchip 54 MHz MEMS XO, AEC-Q100","metaDescription":"Microchip DSC1001DI1-054.0000T: 54 MHz MEMS XO, CMOS output, AEC-Q100 qualified, -40°C to 85°C, 1.8-3.3V supply, standby mode.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Crystals & Oscillators"],"specifications":{"Mfr":"Microchip Technology","Type":"XO (Standard)","Output":"CMOS","Series":"DSC1001","Package":"Tape & Reel (TR)","Ratings":"AEC-Q100","Function":"Standby (Power Down)","Frequency":"54 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"4-SMD, No Lead","Product Status":"Active","lifecycle_stage":"eol_hot","Size / Dimension":"0.098\\\" L x 0.079\\\" W (2.50mm x 2.00mm)","Voltage - Supply":"1.8V ~ 3.3V","Base Product Number":"DSC1001","Frequency Stability":"±50ppm","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"-40°C~85°C","Current - Supply (Max)":"7.2mA","Absolute Pull Range (APR)":"-","Spread Spectrum Bandwidth":"-","Current - Supply (Disable) (Max)":"15µA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.8850","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/6e16d8c0e20d671fdec1bc4732fc9156.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is the DSC1001DI1-054.0000T AEC-Q100 qualified and suitable for automotive use?","answer":"Yes, the DSC1001DI1-054.0000T carries an AEC-Q100 rating.

This makes it suitable for battery-backed or sleep-mode automotive modules."},{"question":"Can I use the DSC1001DI1-054.0000T as a direct replacement for a 54 MHz crystal oscillator?","answer":"The DSC1001DI1-054.0000T is a MEMS-based XO (standard oscillator) with a CMOS output. It can replace a 54 MHz crystal oscillator in a circuit that expects a CMOS-level clock input, provided the supply voltage (1.8V to 3.3V) and footprint (4-SMD no-lead, 2.50 mm x 2.00 mm) match the existing layout. A crystal oscillator typically requires external load capacitors and an inverter — this MEMS XO integrates the resonator and drive circuit in one package, simplifying the BOM."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1001DI1-054.0000T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1001DI1-054.0000T when reusing this data.
